Question

The hershey-chase experiment proved that DNA was hereditary information because

A. radioactive phosphorus in viral proteins was shown not to enter bacterial cells
B. radioactive phosphorus in viral DNA was shown to enter bacterial cells
C. radioactive sulfur in viral proteins was shown to enter bacterial cells
D. radioactive sulfur in viral proteins was shown not to enter bacterial cells

Answer 1

sections of the T2 phage, because sulfur is contained in amino acids but not DNA. ... Thus, theHershey–Chase experiment helped confirm that DNA, not protein, is the genetic material.
